Constructed as an earth-fill dam wall with a brick core in 1932/4, it was extended between 1988 and 1990 by raising the dam wall with the addition of a concrete wave wall and a reinforced earth barrier wall, as well as a surfaced roadway, on top of the original wall.
The dam is fed by the Rietvlei, a river of the Crocodile River (Limpopo) basin, as well as by five fountains and five boreholes.
The Rietvlei Nature Reserve occupies the area immediately surrounding the dam.
